Along the right side of my right foot I have been experiencing pain. It occurs while standing, while sitting, while lying down, and while standing, yes all the time. There is no relief in any position. In my apartment, there are only three places for me to be - in my wheelchair, on the toilet, and, on my hospital bed where I sleep in a sitting upright position. I do have arthritis and I am obese. I have no memory of an actual injury. Pain medication does not provide relief. I am 62 years old, receive SSDI, and am on Medicare and Medicaid. What has me worried now, is that while in bed, the pain and numbness has extended up through the right side of the leg to the knee! What is happening?
